UNHED STATES Fermi @ri icet CHRISTOPHER RIESSNER, OF NEW YORK, N. Y.

COAL-OIL STOVE.

SPECIFICATION forming part of Letters Patent No. 238,528, dated March 8, 1881.

Application filed February 2, 1881.

To all whom it may concern:

Be itknown that I, CHRISTOPHER Rrnss- NER, of New York city, New York, have invented a new and useful Improvement in Goal- Oil Stoves, which improvement is fully set forth in the following specification.

This invention relates more particularly to oil-stoves in which the top of the oil-reservoir, or a portion thereof carrying the wick-tubes. is made detachable, so as to give access to the interior of the reservoir otherwise than by the small filling tube or aperture usually employed. It is frequently desirable to have such access to the interior of the oil-reservoir for various reasons-as, for example, in order to remove sediment that may collect therein, or in case a wick should be accidentally dropped into the reservoir to recover it.

In oil-stoves as commonly manufactured for sale the tops of the reservoir have not been detachable in whole or in part; but they have been permanently secured to the sides, so that the only access to the interior of the reservoir is through the filling tube or aperture. This construction has been adopted mainly for reasons of safety. Oil-stoves have, however, been devised with aremovable cover but they have not, so far as I am aware, entered into general use.

The present invention has for its main object to construct a stove with a portion of the top of the oil-reservoir carrying the wick-tubes detachable, in which the detachable part or Wick-plate is secured in a safe manner, while at the same time it can be readily removed when required.

In the present invention the wick-plate is set into the top of the reservoir, and is retained in position by means of depending lugs attached to a plate which is held down by bolts that screw into nuts formed in or attached to the top of the reservoir. Two of these bolts are ordinarily used. The plate to which the depending lugs are attached is usually made separate from the top or upper part of the stove, and is placed between it and the oilreservoir. The same bolts serve to secure the wick-plate in position and to connect together the upper part of the stove or stove-top and the reservoir.

(No model.)

so that they may serve simply for holding together the parts, and to make a solid connection between said parts, projections are formed on the lower side of the stove-top and on the top of the oil-reservoir, and are arranged to engage with projections on or in openings in the intermediate plate, or section-plate, as it is called herein.

In order that theinvention and the manner of carrying it into effect may be more fully understood, the same will now be described in connection with the accompanying drawings, which form a part of this specification, and illustrale the construction of a stove embodying the invention.

Figure l is a plan view, partly in section, of

the lower portion of the stove, the top being 1 removed; and Figs. 2 and 3, vertical sections of the stove on lines at a; and y y, Fig. 1.

A is the oil-reservoir, the top of which is formed in part by a detachable plate, a, which carries the wick-tubes a, and is called herein the wick-plate. It is preferably of rectangular shape, as shown, and is let into a corresponding opening in the top of the reservoir. The adjacent edges of the wick-plate and reservoir-top are inclined in order to make a close and solid joint, and a small lip projects from the top of the reservoir under the wick-plate for the same purpose.'

Above the oil-reservoir is the section-plate B, on the under side of which are depending lugs 12, which hear at their lower edges upon the wick-plate a.

The stove-top, which rests upon the sectionplate B, is composed of two parts, the body 0, of ordinaryor suitable construction, and a ring, I), to which the latter is hinged at c. The stove-top is secured to the reservoir, and the wick-plate is held in position by means of bolts E, which pass through suitable openings 1n the ring D and section-plate B, and screw into threaded openings in the top of reservoir A. WVhen these bolts are tightly screwed into place, the ring D, section-plate B, and reservoir A are securely united, and the lugs 1) upon the section-plate are caused to press firmly upon the detachable wick-plate a, holding it in position and making a tight and safe joint between it and the top of the reservoir.

In order to make a more solid structure, and

to keep the section-plate from moving sidewisc, projections c are provided on the top of reservoir A, which projections engage with depending projections e on the under side of the section-plate. These projections e e, being held in contact with each other, prevent sidewise motion of the oil-reservoir and section-plate independent of each other. In like manner projections e on the upper side of the sectionplate act with the depending projections c from the ring D. In addition to these projections there are two pins, one, d, depending from the ring D, and the other, d, projecting from the top of the reservoir A, which are caused to enter, from opposite sides, a hole, d in the section-plate. Other devices of a similar character may be used with or instead of those indicated, for the purpose of effecting a solid connection between the parts. In practice, however, these have been found sufficient.

To separate the different parts, and thus to gain access to the oil-reservoir, it is only necessary to unscrew the bolts E, when the stovetop, section-plate, and wick-plate can be removed.

The filling-tube F is formed at the back of the oil-reservoir and in one piece therewith, and is provided with a hinged cover, f. The hinge is formed by the aid of two rounded projections or pins, g, which are or may be cast in one piece wit-h the cover f, and which are held loosely between the curved pieces f, extending from the section-plate and the rim of the filling-tube.

This construction is very simple and cheap.

The section-plate being removable, it is easy to secure the lid in position, or replace it with a new one should it he accidentally broken.

Having now fully described the said inven tion and the manner of carrying the same into eifect, what I claim is 1. The detachable wick-plate forming part of the cover to the oil-reservoir, in combination with the stove-top and devices or bolts serving both to fasten said plate in position and to attach said stove-top to the reservoir, substantially as described.

2. In combination with the oil-reservoir and detachable wick-plate, a plate having depending lugs which bear upon said wick-plate and bolts, substantially as and for the purpose set forth.

3. The combination of the stove-top, oil-reservoir with detachable wick -plate, sectionplate, bolts, and projections or engaging devices upon the stove-top, section-plate, and oil-reservoir, substantially as described.

t. In a coal-oil stove, the section-plate interposed between the stove-top and oil-reservoir, and held in position by the bolts which connect together the stove-top and oil-reservoir, substantially as described.

5. The combination of the oil-reservoir with its filling-tube, section-plate, and the hinged lid to the filling-tube, the hinge of said lid being formed by rounded projections or pins, which fit loosely in openings between the section-plate and rim of the filling tube or portion of the oil-reservoir, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

OER. RIESSNER.
